Unformatted text preview: 1 (default), the host generates ICMP source quench errors when incoming datagrams
are discarded. If 0, these are not generated.
(Debug) Number of bytes of extra space to allocate in buffers for IP headers. Default is
(Debug) If 1 (default), the length field in the IP header of received datagrams is adjusted
to exclude the length of the IP header. This is compatible with Berkeley-derived
implementations and is for applications reading raw IP or raw ICMP packets. If 0, the
length field is not changed.
The default TTL for outgoing ICMP messages. Default is 255.
(Debug) Number of bytes of extra space to allocate in buffers for IP options and data-link
headers. Default is 32.
(Readonly) The ARP cache.
The interval after which ARP entries are discarded from ARP's cache. Default is 300000
ms (5 minutes). (IP maintains its own cache of completed ARP translations; see ip_ire
flush_interval.) file:///D|/Documents%20and%20Settings/bigini/Docu...homenet2run/tcpip/tcp-ip-illustrated/append_e.htm (9 of 16) [12/09/2001 14.48.06] Appendix E: Configurable Options arp_debug
(Debug) If 1, enables printing of debug output by the ARP driver. Default is 0.
The default TTL for outgoing UDP datagrams. Default value is 255.
If 1 (default), UDP checksums are calculated for outgoing UDP datagrams. If 0, outgoing
UDP datagrams do not contain a checksum. (Unlike most other implementations, this
UDP checksum flag does not affect incoming datagrams. If a received datagram has a
nonzero checksum, it is always verified.)
Largest port number to allocate for UDP ephemeral ports. Default is 65535.
Starting port number to allocate for UDP ephemeral ports. Default is 32768.
A process requires superuser privilege to assign itself a port number less than this.
Default is 1024.
